[The Effect of Family Member Reminders on Reducing Anxiety and Unplanned Extubation in ICU Patients].

ABSTRACT

BACKGROUND: Patients with endotracheal intubation often experience anxiety because they are unable to express their needs freely. However, the family members of these patients are able to provide encouragement, comfort, and substantive support. PURPOSE: The aims of the present study were (1) to compare the anxiety scores, vital signs, and incidence of unplanned extubation (UE) between the two comparison groups; (2) to compare the differences in vital signs before and after the intervention in the experimental group; and (3) to explore the satisfaction of patients in the experimental group with the intervention. METHODS: A quasi-experimental, pretest-posttest design was carried out. A convenience sampling was adopted to recruit patients with endotracheal intubation in intensive care units (ICUs). The experimental group listened to the UE-prevention reminders of their family members for three times a day for 4 days. The control group was provided with usual care. RESULTS: (1) No significant difference was observed in the anxiety scores between the two groups (t = -1.282, p = .205). (2) A repeated-measures analysis found no significant difference in vital signs, taken nightly at 10 p.m., between the experimental and control groups (p > .05). (3) The experimental group registered significantly lower heart rates, systolic blood pressure, diastolic blood pressure, and mean arterial pressure after the conclusion of the intervention (p < .05). However, no significant pre-test / posttest difference in breathing rate was observed for this group. (4) A large majority (89%) of the experimental group expressed satisfaction with the intervention treatment program. CONCLUSIONS / IMPLICATIONS FOR PRACTICE The present study, which used a DVD of family reminders encouraging and reminding patients about intubation safety, achieved a very high level of patient satisfaction and reduced their anxiety-related vital signs. The results may serve as a reference for providing intervention treatment to patients with endotracheal intubation in ICUs.
